Briefly stated, the plug is formed with a 4c in the drawings: shank 23 surmounted by a head 2 1 and Figure 1 is a perspective view showing formed at its outer end with a cup 25. EX- the manner in which the tool may be emtending from the head are spaced gripping ployed in connection with a vise for tempowings 26. A bond cable is indicated at 27, rarily connecting a bond plug with a bondthe bond plug being particularly designed 10o ing cable, for rendering practicable the use of dislt igure 2 is a fragmentary sectional View carded electrical cable in connection thereshowin the manner in which the tool may with. In using cable of this character it has be emp oyed tor upsetting the plug in on been found expedient to first temporarily gagement with a rail and permanently conconnect a pair of the bond plugs to the ends 5a necting the plug with the bonding cable, of the cable. The cable with the bond plugs Figure 3 is a fragmentary sectional view thereon may then be easily carried to the showing the manner in which the bond plug point of use, when the operation of permais supported by the anvil of one of the jaw nently connecting the bond plugs with the heads of the device as suggested in Figure 1, cable is completed at the time the plugs 11c 55 and are engaged with the meeting ends of the Figure 4: is a fragmentary sectional view track rails. As will now be seen, he head 13 of the tool. is so formed that, in the prac tlcal use thereoi, said head may first be engaged in a vise, as suggested in Figure l, for

supporting the head in upright position, the shoulders 15 of the anvil 14: abutting the upper edges of the vise jaws for ri 'idly holding the head against downward movement through the jaws. The vise illustrated is,,.o;f course, conventionally shown. After the head has been thus fixed upon the vise, the shank 23 of the plug is fitted in the opening 16 of the anvil, when one end of the cable 27 is placed between the wings 26 of the plug. A hammer is then employed for bending the wings over in overlapping relation about the end portion of the cable, tempo.- rarily connecting the plug to the cable. A. plug is, of course, in the inannerindicated, secured upon each end of the cable, when the bond is ready for engagement with the meeting ends of a pair of rails. 'To accomplish this operation, the shanks 23 of the plugs are first fitted through the usual openings provided in the rail webs when the present device is used to operate upon each plug for firmly connecting the plugs with the rails. To thus operate upon each plug, the jaws 12 of the device are, as shown in Figure 2, arranged to straddle the rail when the upsetting tool l'Z of the head 13 of one of the jaws is engaged in the cup, 25 while the inner end of the swedge 20 is fitted over the inwardly bent overlapping wings of the plug. Then, while the levers 10 or". the device are firmly held to clamp the swedge and upsetting tool in engagement with the plug, the swedge is struck several sharp blows. As will be preciated, this will cause the upsetting tool to overturn the shank of the plug into engagement with the rail web while the concave face 22 of the swedge will coact with the wings of the plug to complete the bending operation of said wings sothat the wings will be caused to tightly bind against the cable and effectually secure the cable in engagement with the plug. Thus, at one operation, the plug will not only be seci'uely engaged with the rail but also, the plug and cable will be firmly connected, the union between the cable and plug being such that all moisture will be excluded from the joint therebetween, Accordingly, corrosion can not occur at the joint to cause defective conduction.

Having thus described the invention, what is claimed as new is z :1. A bonding tool including coacting j aws one provided with a fork, a swedge mounted between the arms of said fork, a pin extendingbetween the fork arms securing the swedge thereon, and a coacting upsetting tool carried by the other of said jaws.

2. In a bonding tool, the combination of pivotally connected levers having coacting jaws. one provided with a head having an opening therethrough and forming an anvil, an upsetting tool seated in one end portion of said opening, the outer end portion of the opening being adapted to accommodate a bond plug resting against the anvil, and a coacting swedge carried by the other of said j aws-.

3. In a bonding tool, the combination of pivotally connected levers having coacting jaws one provided with a fork, a swedge carried by said fork, and a coacting upsetting tool mounted upon the other of said jaws.

t, In a bonding tool, the cornbinationof pivotally connected levers provided with co acting jaws one formed with an elongated head having an opening therethrough, the outerend portion of said head providing an upstanding anvil, an upset-ting tool carried by the inner end portion of the head seated op i g, and a co c ing Swvedge mounted upon the other of said jaws.
